Description: |
| The ratchet action in this wrench is two crown-ratchet rings held in engagement by a coil spring. The patented feature is that one of the rings has a second set of teeth facing in the opposite direction. The ring can be removed from the ratchet head and turned over, thereby reversing the direction of the ratchet action. |
